I wonder if it is the same thing for us (yes I know our engines are different)? I haven't heard of anyone trying this approach instead of drop in pistons... Really wish someone would if only to satisfy my curiosity.

This is correct. That piston failed due to heat causing the ring to bind. I have had it happen in the past and sometimes it's tune related (it was on mine) but sometimes it's other factors that come into play.
Modding is expensive.
